Title: Battery operated industrial trucks
Inventor: TEDD DAVID CLIFFORD
IPC: B60L15/04
Filed: 1968-10-30
Abstract: 1283694 Control of D.C. motors EATON YALE & TOWNE Inc 17 Oct 1969 [30 Oct 1968] 51375/68 Heading H2J In an industrial truck, the forks are tilted forwardly by closing contact 14 to energize relay 15 associated with delay network 16. Contacts 15a are closed to complete a reduced power circuit to pump motor 27 through diode 24 from the lower half of battery 11. To tilt the forks rearwardly, contacts 21 are closed to energize relay 22 which operates contacts 22a. The motor 27 again receives reduced power from the upper half of the battery through diode 26. This arrangement ensures that the battery is discharged evenly, and may be applied to other complementary pairs of functions such as shifting the forks to the side of the truck. To lift the forks, contact 19 is closed and relay 22 is energized immediately through diode 18 whereby the motor operates at reduced power. After a period, relay 15 is energized through diode 17 so that the motor receives the full voltage of the battery.

Filed: 1971-11-08
Abstract: 1362420 Timing ignition DUCELLIER & CIE 8 Nov 1971 [10 Nov 1970] 51769/71 Heading F1B [Also in Division H1] In a double-action vacuum advance capsule 2 for an ignition distributor for an internal combustion engine, two resilient members 12, 18 act independently of each other against the vacuum in the chambers 6 and 5 respectively and also bring diaphragm 7 into a rest position, the rest position being adjustable and the force of members 12, 18 being adjustable independently of each other. If a vacuum is drawn in chamber 5, diaphragm 7 moves in the direction of arrow F1 and its movement is resisted by spring 18 being compressed between the head 19 of plunger 11 attached to diaphragm 7 and the bottom 13a of cup-shaped element 13 engaging flange 15a of ring 15. The force of spring 18 is adjusted by screwing plunger 11 in or out of traction rod 9 secured between diaphragm 7 and the distributor plate (not shown). If a vacuum is drawn in chamber 6, diaphragm 7 moves in the direction of arrow F2 and its movement is resisted by spring 12 being compressed between the bottom 13a of element 13 and cavity 16 of support member 17. The force of spring 12 is adjusted by screwing member 17 in or out of sleeve 20. The rest position of diaphragm 7, when chambers 5, 6 are at atmospheric pressure, as shown in Fig. 1, is adjusted by screwing in or out ring 15 in sleeve 20. With the above, an advance, curve L2, and a retard, curve L1, of the moment of sparking as a function of vacuum and speed of the engine can be obtained as shown in Fig. 4. In a second embodiment, Fig. 2 (not shown), the two springs are inside the distributor housing and are connected between the wall of the housing and two pivoted levers 39 and 44 which both act on the end of the traction rod 35 joined to the diaphragm 30, each spring 37, 42 coming into action on diaphragm 30 moving in different directions and being taken out of action by a stop 40 against which levers 39, 44 rest in the opposite directions. Stop 40 is adjustable e.g. an eccentric, and springs 37, 42 are fastened to casing 1 by members 38, 43 which are adjustable. A third embodiment, Fig. 3 (not shown) is as the second embodiment except that the end of the traction rod is not linked to the distributor plate but to a lever 49 linked to arm 46 of the interrupter 47.

Title: Carbon monoxide laser
IPC: H01S3/223
Filed: 1971-11-08
Abstract: 1367141 Lasers NORTHROP CORP 8 Nov 1971 51816/71 Heading H1C The active medium of a room temperature carbon, monoxide laser comprises 0À5-5À0 torr CO, 25-500 torr He, 2-50 torr N 2 , and O 2  or NO in an amount in the range 0À01-2% of the amount of CO used. A further 1-5 torr of Xe may be added, and mercury vapour may be introduced as in Specification 1,341,081. The amount of CO used is relatively high, and its dissociation into C and O is minimized by the added O 2  or NO. The He is used to cool the gas mixture as it has a good thermal conductivity. The N 2  is dissociated by the pumping discharge to N + N, and the recombination energy of these atoms is transferred to the CO, thus assisting the excitation of the CO and reducing the number of high energy electrons which might otherwise dissociate the CO. The Xe reduces the electron temperature of the discharge to a level at which more electrons can be absorbed by the CO and N 2 , and because Xe has a low ionization potential it too absorbs electrons which might otherwise dissociate the CO. The laser may use axial or cross flow, and in the latter case a closed gas system may be used. The laser tube may be water cooled to maintain room temperature operation. When mercury is to be added each discharge electrode is immersed in a pool of mercury.

Abstract: 1364155 Pile fabrics SERPO NV 9 Nov 1972 [12 Nov 1971 3 Nov 1972] 51845/72 Heading B2E [Also in Division D1] A pile fabric is formed by the steps of applying a layer of foam-forming reaction mixture on to a temporary or permanent supporting layer and electrostatically implanting pile fibres into the foam layer before it hardens completely. As shown a substrate 1 is opened into a tube 2 and sprayed with reaction mixture from concentric outlets 5, 6 and 7. The tube is then flattened and pile is applied from an electrostatic device 10. The fabric is cured in an oven 11 and loose pile is removed by suction at 12. The support layer may be wound up at 13 or if of suitable material to which the foam bonds it maybe retained. The pile penetrates the foam and is anchored in place by the skin which forms on the foam. This penetration may be altered by changing the distance between the devices 3 and 10 or altering the electrostatic field. The upper surface of the foam may be deformed by rollers between the devices 3 and 10 to texture the pile. A knitted or gauze fabric 17 may be introduced into the foam before implanation to vary the texture and increase the strength or it may be added before the foam to improve the strength without texturing. Two flocking devices 10 may be provided to produce designs by colour or by pile length.

Abstract: Particles of a thermoplastic resin comprise a core of a homopolymer of a first monomer of the formula <FORM:1097562/C3/1> in which X1, X2, X3 and X4 are the same or different and each is a hydrogen or halogen atom, at least one of X1, X2, X3 and X4 being other than hydrogen, encapsulated with from 0.1 to 10% by weight, based on the total weight of polymer, of a copolymer of said first monomer and a second monomer of formula <FORM:1097562/C3/2> in which X1, X2, X3 and X4 are as defined above, different from the said first monomer, the copolymer having a softening point lower than that of the homopolymer.  The particles may be formed by polymerizing the first monomer to a partial conversion of at least 70% and then adding the second monomer, in an amount less than the amount of second monomer remaining, and continuing polymerization.  Alternatively, the first monomer is completely polymerized before adding a further amount of said monomer and a minor proportion of the second monomer. In the example, the first procedure is employed, the first monomer being vinyl chloride and the second vinylidene chloride.  The process is carried out in an aqueous suspension containing lauroyl peroxide and hydroxypropyl cellulose. The resulting resin is fused with dioctyl phthalate and tin butyl mercaptide to form a sheet.

Figs.3A-3C provide a flow chart of an embodiment in which input CDP trace sets have already been corrected for normal moveout. Blocks 40-44 effect step a by a cross-correlation technique. Step b is carried out at 45-47, the statics common to a given surface location being collated and step 46 being iterated a fixed number of times. Step c is done at 49 by a method involving forming trace static estimates relative to the mean of the surface statics associated with any CDP set then determining the differences between the trace static estimates and the measured trace statics Fig.3D (not shown). Steps d, e, f, g are represented by blocks 50, 52, 54, 56 respectively. Blocks 55, 55a, 55b, 62 correspond to step h. Blocks 55, 56, 57, 60, 62 correspond to step i. Measured trace statics which differ appreciably from the estimated statics are considered unreliable and the associated traces are corrected using the estimated values, as represented in blocks 57, 58, 59.
